vide a hinge of this type of simple con struction and eilicient inoperation, which hinge may be applied to doors swinging in bothdirections and is adapted to automatically return the door to closedposition when opened in either direction, and is further apt-ed to holdthe door in fully opened position. A specific embodiment of my inventionillustrating this and other advantages is described in detail in thefollowing specification and is illustrated in the accompanying drawingsforming part thereof and illustrating a preferable embodiment orthemvention.

In them drawings, Figure 1 is a fragmentary view in elevation, partly insection, of the ower inner end of a swinging door showing my closerhinge applied thereto as Fig. 2 is (a horizontal sec a floor hinge.tiona'l view taken on the line 22 of Fig. 1.

Fig. 3 is a view in elevation of the stationary pivot member detached.

Referrin to the drawings by numerals, 1

indicates a our of the double swinging type. At a point below the doorand adjacent its inner orig cl, a floor plate 2-is fastened to the flooror treshold of a door casing in which is rigidly mounted a pivot member3 whose squared lower end 4: is seated in a similar recess formed in thefloor plate and is preferably upset therea ainst. This pivot mema socket5 therein and her is provided wit with an annular head 6 concentricthereto and extending upwardly therefrom, the edge or this annular headbein cut away at one aid; to form complementa arcuate cam surfaces 7extending upwardl and in opposite directions from an interme iateandcommon low point 8. The high points of these cam surfaces terminatein the flat surfaces 9 of the head.

lower ball race within the socket 5 0 V p 1 member. Thespindle 15, ofcourse, extends Extending up within a recess formed in the bottom of thedoor 1 is a bracket plate or bar 10 havin its upper end terminating inan arm 11 an having also a lower arm 12 seated against a cutout portionat the under edge of the door, and being split at its end to form a benttongue 12'} seating within a, slot 13 formed in a bottom bar 14, whichis secured to the bottom recessed edgeoi the door and to the lower arm12 of the bracket- 10, the forward or inner end of this bar seatingunder and against the head 6 of the 1 pivot member.

A spindle 15 having its upper portion threaded and its upper extremityflattened as at 16, is 'seated at ,said upper end in an aperture formedin the upper arm 11 and corresponding in shape to the shape of theflattened end of the spindle so that said spindle is held by saidbracket arm against rotary movement. The flattening of the upper end ofthe spindle forms shoulders which rest against the under face of the arm11 or the bracket. The lowerend of the spindle seats in the socket 5 orthe pivot member 3, its end resting upon and being supported by a bailrace formed of two bearin washers 17 inciosing a plurality of steel hals 1'8.

Slidably mounted on the lower portion of the spindle 15 is a bearingsleeve 19 against which bears the lower end of a coiled spring 20encircling the spindle and engaged at its upper end by an adjusting andtensionihg nut 21 threaded on the upper end of said spindle. A look nut22 is also preferably provided to codperate with the adjusting nut 21. vi r The bracket bar 10 adjacent its lower end is provided with anelongated slot 23 within which slides the flattened end 25 of a stud 24-whose other end is threaded into the portion of the bearing sleeve 19,and on which stud is journaled an anti-friction roller-26.

It will Patented Mar. id, 19313..

be evident from the foregoing that the door is journaled on' the pivotmember 3 by reason of the s indle 15 carried byth'c door through theracket resting upon the Y the pivot in the line oi axis oi the pivotstud, and the bearing part 19v carried thereby likewise lies in saidline oi? axis. As this hearing portion is connected to the bracketthrough the connection of the stud 2d therewith, it will be obvious thatas the door is swung, the bearing sleeve 19 and its anti-friction rollercontact 26 will swing with the door. 'ihis roller contact is-sopositioned that when the door is closed, it will rest upon theintermediate low part 8" between the complemental cam surfaces? of! the,pivot head; 'lhese cam surfaces each extend in an arc, with the pivotmember has the center, the combined arcs of the complemental camsurfaces being preferably slightly less than a semi-circle. When thedoor is swung in either direction from closed position, it will,

' tain the door in fully opened position. llt

ill

the door is not swung entirely open, or .in an arc of less than ninetydegrees, the antifriction roller will not pass over the high point ofthe cam surface, and-releasing said door, will, through the power of thecompressed spring 20, move said roller downwardly against the inclinedcam surface and return the door to closed position I find that inpractice the pressure of the compressed coiled spring 20 serves totrictionally hold the anti-frictionroller 26 a ainst the top flatsurface of the annular hea so that the door is held in opened positionwhen, swung in either direction, but it is obvious that this flat edgeat points at substantially ninety degrees to the intermediate lowportion 8 of the cams, may be provided with a slight concavity intowhich the antidriction roller will be pressed by the spring to lock thedoor against closing movement.

A door to which my closer hinge is applied is, oi course, provided witha'stud at its opposite end seated within a socket formed in the doorcasing. It is obvious that in mounting such a door provided with mycloser hinge, the entire hinge including the door plate may be firstsecured to the door and then the door moved to bring its upper studwithin the socket in the casing of the door. The lower end of the doorcan 7 then be positioned to bring its floor plate in the line of axis"of the upper stud, and said intern What I claim, therefore, and desiretosecure by Letters Patent is:

1. In a device of the character described, a stationar pivot memberhaving a socket formed t erein and having a concentric an-' nular headextending. outwardly from said socket and provided with complemental camsurfaces thereon extending in opposite directions from an intermediatelow point, a door, a spindle connected to said door extending in theline of axis of said pivot member and having its end journaled in. thesocket there. of, anti-friction thrust bearings within said socket torsaid spindle end, a bearing member guided on and movable longitudinallyof said spindle and having a contact member positioned to engage saidannular head and to seat in the intermediate low point of said camsurfaces when the door is in closed position, and spring meanscotiperating with said bearing member to hold it in engagement with saidcam surfaces.

, 2. In a device of the character described, a stationary pivot memberhaving a socketformed therein and having a concentric an-v nular headprovided with complemental cam surfaces thereon extending in oppositedirections from an intermediate low point, a door, a spindle connectedto said door extending in the line of axis of said pivot member andjournaled in the socket thereof,

anti-friction thrust bearings within said socket for said spindle end, abearing member movable longitudinally of said spindle and having, ananti-friction contact member positioned to engage said annular head andto seat in the intermediate low pointof said cam surfaces thereof whenthe door is in closed position, and spring means for moving saic bearingpart to force its contact member into engagement with said cam surfaces.

3. ln a device of the character described, a stationary pivot. memberhaving a socket formed therein and having a concentric annular headextending outwardly therefrom and provided with 'complemental camsurfaces extending in opposite directions from an intermediate low ointand terminating in flat surfaces at then high points, a door, a s indieconnected to said door extendin in t e line of axis of said pivot memberan having its end journaled in the socket thereof, anti-friction thrustbearings within 1,ose,171

said socket for said spindle end, a bearing member guided on and movablelongitudinally of said spindle and having a part positioned to engagesaid annularhead and to seat in the intermediate low point of said camsurfaces when the door is in closed position, and a closer springcooperating with said bearing member to move itto engage with said camsurfaces.
